$\frac{-1}{\sqrt{1-\left(\frac{x}{a}\right)^2}}\frac{d}{dx}\left(\frac{x}{a}\right)$

Learn how to solve problems step by step online. Find the derivative of arccos(x/a). Taking the derivative of arccosine. The derivative of a function multiplied by a constant (\frac{1}{a}) is equal to the constant times the derivative of the function. Multiplying fractions \frac{-1}{\sqrt{1-\left(\frac{x}{a}\right)^2}} \times \frac{1}{a}. The derivative of the linear function is equal to 1.
